GitHub repo: https://github.com/satyasekharcvb/lwc-local-dev.git With the release of a new beta version of Local Development, you can now build Lightning web components faster than ever before! You can now render changes, iterate rapidly, troubleshoot errors, and even connect with data from your org by spinning up a local development server on your machine. In this session, we build Lightning web components in real time. The exciting new capabilities we showcase will enable you to be an even more productive developer. In this CodeLive session we: - Spin up a local development server from the CLI to rapidly edit and view components - Observe how a rich error handling experience simplifies testing and debugging - Learn how to proxy data from an org for more context and fine-tuned development
